Vehicle-to-Vehicle (V2V) communication is a vehicular communication technology to reduce traffic accidents and congestion. To protect V2V communication, multiple security standards have been developed. This article provides an overview of the China V2V security draft standard and compares it to the American IEEE1609.2 V2V standard and to the Security Credential Management System (SCMS).
The article provides an overview of the Chinese cryptographic algorithms used in the China V2V standard, and points out differences in the certificate format, such as the lack of implicit certificates in the China V2V standard. The China V2V PKI architecture is similar to the American SCMS, however, the Chinese system utilizes a set of Root Certificate Authorities (CA) that are trusted via an out-of-band channel whereas the American SCMS supports elector-based addition and revocation of Root CAs.
Note that the China V2V design work is still on-going, and it is expected that the standard will have slight changes in its final version compared with the draft discussed in this article.
